It looks very tranquil.... I'd agree with Brian on some points. I think it'd look better with a little more variation. The trees in the distance seem to be the same model placed repeatedly. You might consider rotating it a random amount for each placement; this might conceal the fact that it's the same one. Brian's comments about the composition are well taken, and I'd add that sometimes a centered composition can add to a feelilng of sedateness and if that's what you're going for, go for it. That said, I'd agree with his suggestions. Very nice work, though. I really like the mood you've evoked. - Chip
